Objectives

To discuss present knowledge about Mediterranean diet and cardiovascular diseases.

Design

Review of existing literature.

Setting and Results

Epidemiological studies as well as randomised dietary trials suggest that Mediterranean diet may be important in relation to the pathogenesis (and prevention) of CHD. For instance, a striking protective effect of an ALA-rich Mediterranean diet was reported in the Lyon Diet Heart Study with a 50 to 70% reduction of the risk of recurrence after 4 years of follow-up in CHD patients. According to our current knowledge, dietary ALA should represent about 0.6 to 1% of total daily energy or about 2 g per day in patients following a Mediterranean diet, whereas the average intake in linoleic acid should not exceed 7 g per day. Supplementation with very-long-chain omega-3 fatty acids (about 1 g per day) in patients following a Mediterranean type of diet was shown to decrease the risk of cardiac death by 30% and of sudden cardiac death by 45% in the GISSI trial.

Conclusions

In the context of a diet rich in oleic acid, poor in saturated fats and low in omega-6 fatty acids (a dietary pattern characterising the traditional Mediterranean diet), even small doses of omega-3 fatty acids (about 1 g EPA + DHA the form of fish oil capsules or 2 g α-linolenic acid in canola oil and margarine) might be very protective. These data underline the importance of the accompanying diet in any dietary strategy using fatty acid complements.
